. '0 all whom it may concern:

Be it known that I, FERDINAND J. H. Freon, 'a citizen of the United States of America, residing at Tamaqua, in the county of Schuylkill and -State of Pemisylvanla, have invented new and useful Improvements in Film-Winding Apparatus, of which the following is a specification. I

This invention relates to film-winding apparatus for moving picture machines and it consists in the provision of identically formed reels which are interchangeably associated in the upper and lower magazines,

the object of the invention being to construct winding apparatus of this character wherein the film from the upper magazine can be wound onto the reel in the lower magazine so that the front end of the film will be disposed inwardly of the innermost wound portion, means being employed for revolubly supporting the lower reel and for-fixing the upper reel so that on winding the film from the upper to the lower reel it can beu'n coiled from the upper reel from the innermost wound ortion.

A still furt er object of the invention is to construct each reel of the winding apparatus so as to prevent damaging wear and tear on the film and to construct each reel so as to obviate any abrupt or injurious bending of the film in the'winding operation.

this specification and in which like numerals of reference indicate similar parts in thein the upper ,and lower magazines, the said magazines being shown in sectlon, Fig. 2

is a detail section through a portion of the upper magazine and through the reel. Fi

3 1s a perspective view of the film gui e in the upper magazine. Fig. 4 is a perspective view of the reel support in the upper magazine. Fig. 5 is a section through the reel in the upper ma azine showing the manner of threading t e front end of the film over the film guide. Fig. 6 is-a longitudinal section therethrough taken on the line 6-6 of Fig. 5; Fig. 7 is a view similar to Fig. 5 showing the manner of threading the film into the reel of the lower magazine. Fig. 8 is a section through the reel in the lower magazine showing the manner of fixing the same with the winding shaft.

In the drawings, forming a portion of permit of the interchangeable association of the reels in theupper and lower magazines. It is believed that a description of onereol will suflice for the description of both and it may bedescribed that each consists of the spaced film-guiding plates 1 which are apertured centrally for a purpose to be hereinafter described. Each guide plate 1 is provided on its outer surface with a central collar 3 which extends entirely around the aperture. Diametrically opposite members 4 are arranged at the sides of the said guiding plates, and as illustrated, each member is formed with an annular concavity or race- ]way 5 in which the antifriction bodies 6 are arranged. The members 4: are apertured centrally and each aperture has its walls formed to provide radial notches 7. for a purpose to be hereinafter explained. An annular series of rollers 8 form the hub of the reel and as illustrated, each roller is provided at its ends with trunnions 9 which extend throughcorrespondingly formed passages in the members 4. The rollers entirely occupy the space between the plates land at the ends the rollers have fitted thereto small collars-10 which engage the walls of the apertures in the plates 1. This construct-ion is such that the platesmay revolve independently of the members 4: The

Each reel is identical in construction to i rollers are arranged in pairs, each pair being separated from each other by a spacing element 11, fastening devices 12 being engaged with the said spacing elements at the ends thereof and withthe members ,4.

The upper magazine 13 is provided at its bottom with a support 14 on which the film guide 15 is mounted, fastening screws or such equivalent devices 16. being employed for holding the film guide fixed to the support. The support 14 is provided with an annular groove 17 which receives .the projecting trunnions of the reel as shown in Fig. 2 of the drawings; The support is provided with a second annular groove 18 which receives the ofiset race-formin portion of the member 1. The filmguide 15 consists of a horizontally disposed body member 19 on which the supporting brackets 20 and 21 are formed. A guide roller 22 is arranged at an angle of forty-five degrees approximately to the body member 19 and it 1s 0 eratively journaled 1n the brack- 21. The bracket 21 is formedride an upwardl extending film guide 24: which extends a ove the lowest point of the film-guidin roller 22. In order that the reel can be iield stationary in the upper magazine during the unwinding operation of the film from the upper reel to the lower reel, lugs or equivalent fastening devices are employed. These lugs are formed integral with the body member 19 of the film guide and they fit the correspondingly formed notches 7 in the lowermost guiding plate 1 in the upper reel. The body member 19 of the film guide is provided with a film-guiding slot 25 which is located imme-.

C diately in line with the slot 26 in the support Hand in line with a similar slot 27 in the bottom of the upper magazine.

The lower magazine 28 is provided with a winding shaft 29 on which is mounted a driving pulley 30 which may receive its power from any sourceof supply as is obvi-ous, but preferably from the driving shaft of the picture machine. The driving shaft 25) has fixed thereto a clamping member 31 which is somewhat similar in construction to the previously described supportcl l. A movable clamping member .32 is mounted on the shaft and as illustrated, aclamping nut 33 isadjustable on the shaft and may be brought to bear against the member 32 to move it toward the companion member 31. As hereinbefore described, each reel is identical in construction so as to permit of their interchangeable association with the upper and lower magazines of the picture machine. The members 34 in the reel of the lower magazine are confined between the clamping members 31 and 32. These clamping members are provided with looking pins 35 which extend longitudinally with the axis of the shaft so as to fit in the notches 7. This construction permits the reel to-be o-peratively associated with the winding shaft in the lower magazine so as to cause the reel to rotate with such shaft.

In the operation of my improved filmwiuding apparatus, I place an empty reel in the lower magazine and a wound reel in the upper magazine. In winding the film first onto that reel which is to be placed in the upper magazine I take the front end of the film and extend it through. the opening in the hub of the reel and passing it between the rollers of the" diametrically opp'osite pairs, as shown at 36 in Fig. 7 of the drawings, and I then wind the filmabout the hub, as shown, confinin the front end 37 between the rollers an the adjacent wound portion of the film. After the film has been wound upon the reel as described, the front end 37 is drawn from between the rollers and the said adjacent wound portion of the film and it is then threaded over the film-guiding roller 22 and through the slots 25', 26 and 27 and then through the slot in the lowermost magazine. The film is then confined to the hub of the lower reel, as illustrated in Fig. 7 of the drawings. After the film from the reel of the upper magazine has been started onto the reel in the lower magazine as hereinbefore mentioned, power is applied to the winding shaft 29 to wind the film from the upper reel to the lower reel. As stated,

the upper reel is stationary with the exception of the film-guiding plate ,1 and on winding of the lower reel the film may be drawn from the center of the upper reel and then associated with the lower reel so that the operator can substitute one reel for the other after the winding 0 eration.

In view of the fact -t at the reels are 'a film-guiding portion movable about the said hub portion, a support removabl engaged with the hub portion and he ding the same against movement with the said film-guiding portion, the said support having a film-guiding slot therein, a second reel having an apertured hub portion and a movable film-guiding portion, a revolving support, means on the su port for engagement with the hub portion of the second reel to cause the same to revolve with the support, and a film-guiding element on the first support for directing the film from the first reel onto the said second reel.

2. In film-unwinding mechanism, a revoluble film holder centrally apertured, a stationary support therefor coaxial with said aperture, said support havin a film-guiding slot therein, and film-gui ing means arranged to guide the film from the inner turn of the film ,coil toward said slot.

Intestimony whereof I afiix'my signature in presence 0 two witnesses.
